Here's a breakdown:

* Landforms are natural features on the Earth's surface, like mountains, valleys, plains, deserts, and islands.

* Waterforms are natural features on the Earth's surface consisting of water, like oceans, lakes, rivers, and seas.

While some landforms might be surrounded by water, and some waterforms might be surrounded by land, these are different types of features on the Earth's surface, making them opposites in a general sense.
